It's OK, I like the sound but cringe a tiny bit at the Anglicized spelling. I prefer
Eithne to be prn Eth-na (it is the most common pronunciation also) so I'd never use that spelling for
Enya. I did know girl in college who spelled her name
Aine but said it
Enya which I liked - again confusing.
Enya's music is OK, I find it a bit twee.
